maxdb_ping - Pings a server connection, or tries to reconnect if the connection has gone down

       Procedural style

SYNOPSIS
       bool maxdb_ping (resource  $link)

DESCRIPTION
       Object oriented style
       bool maxdb::ping (void  )

	Checks	whether  the  connection  to the server is working. If it has gone down, and global option maxdb.reconnect is enabled an automatic
       reconnection is attempted.

	This function can be used by clients that remain idle for a long while, to check whether the server has closed the connection  and  recon-
       nect if necessary.

RETURN VALUES
	Returns TRUE on success or FALSE on failure.

EXAMPLES
       Example #1

	      Object oriented style

	      <?php
	      $maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");

	      /* check connection */
	      if (maxdb_connect_errno()) {
		 printf("Connect failed: %s
", maxdb_connect_error());
		 exit();
	      }

	      /* check if server is alive */
	      if ($maxdb->ping()) {
		 printf ("Our connection is ok!
");
	      } else {
		 printf ("Error: %s
", $maxdb->error);
	      }

	      /* close connection */
	      $maxdb->close();
	      ?>

       Example #2

	      Procedural style

	      <?php
	      $link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");

	      /* check connection */
	      if (maxdb_connect_errno()) {
		 printf("Connect failed: %s
", maxdb_connect_error());
		 exit();
	      }

	      /* check if server is alive */
	      if (maxdb_ping($link)) {
		 printf ("Our connection is ok!
");
	      } else {
		 printf ("Error: %s
", maxdb_error($link));
	      }

	      /* close connection */
	      maxdb_close($link);
	      ?>

       The above example will output something similar to:

       Our connection is ok!
